Abstract
PURPOSE: To improve the working environment, to rapidly, surely execute the repair, and to extend the workable life of the tapping spout, by setting the inner frame provided with the vibrating mechanism in the tapping spout after the tapping work, by filling up the gap between the inner frame and the undamaged part with the spout material, and then, by heating and curing the spout material.
CONSTITUTION: The unsolidified residual iron 3 in the bed 9 of the tapping spout 2 and the sticking substance 3' like as the ground metal, etc., sticking on the side wall 10, are removed away at an early stage, and the inner frame 6 is set at the specified position so as to form the gaps 7, 7'. The spout materials 8, 8', hardly containing moisture is interposed between above gaps 7, 7'; then, the vibrating mechanism 5 is started to vibrate the inner frame 6 for compacting the spout materials 8, 8', to a specified density. Next, before or after detaching the inner frame 6, the spout materials 8, 8', is heated to above about 300°C for 20W60 minutes, and is hardened. According to this method, the damaged part of the tapping spout, etc., can be rapidly, surely repaired, so that the repairing work can save the labor.
